Thing is, that giant icicle I've just climbed up ismade of frozen water,

Glaciers are not formed from frozen water.

冰川并不是由冻水形成的

They are made from snow.

它们由雪变来

Every snowflake is formed from dozens of delicate ice crystals.

No one has ever found two that are the same.

每人能发现有两片一样的

Individual snowflakes may be fragile

but put enough together and they create one of the most awe-inspiring sights in nature.

但是聚合起来它们能创造 一个自然界中令人敬畏的景象

Every year, around a million avalanches thunder down the Earth's mountains.

when it comes to reshaping the Earth, they barely even scratch the surface.

When snow turns into ice,
